Application fned Maren 25,1881. semi No. 32,418. (No model.) i 4 Toallwhom it may concern: j

Be it known that I, CHARLES STANFORD UP-l TON, a citizen of the UnitedStates, residingat New York, in the county and State of New York, haveinvented certain new and useful Improvements in'Lamps, of Which thefollowing is a specification. f y,

My invention relates to an improvement that is adapted to be used inconnection with central-draft lamp-burners in general, but is morepractically applicable towhat is known in the trade as the Rochesterlamp, and it is in connection with this lamp that I will show and idescribe it. f

My invention'consists ina short perforated sleeve or collar tting aroundthe upv.per end of the inner wick-tube, having a horizontalinwardly-projecting flange extending overk the top of the latter, so'that the oil, when it leaves the wick,`instead of creeping by means ofcapillary attraction over the top ot' the inner wick-tube, will beabsorbed through the perforations inthe aforesaid sleeve or collar, andthence 'pass down on the outside of' d and W is a cylindrical wickextending down into the oil-chamber, I being the inner wicktube, havingan annular depression, fi, on thel outside, forming an'annular shoulder,fi', on the inside thereof, and O the outer wick-tube,

' which guides and holds thepwck W.

y C is a collar,whichencircles andl retains the wick, and R is thewickraiser,for the purpose of raising and lowering the wick whendesired. f Tis the perforatedthimble for spreading and equalizing theaircurrents which come up in the inner Wick-tube, I, supported on theshoulder i of the latter, having bossesoroutward projectionst. Betweenthe th'imble and substantially as described. 1 l CHARLES S. UITON.

small inwardly-projecting ange, F, which rests upon the top of theinterior wick-tube, I. When the wick becomes saturated and tends PATENTOFRICR.

wick-#tube is thus formed the annular air@ i to ,give off any oil fromVitsinner surface,.it A' will be absorbed through the perforationsfs ofthe Sleeve S, from whence it will flow down and upon the outside ofk theinner wick-tube,- I, and back into the oil-chamber. If, however,any oilreaches the top of the sleeve'S on the inside of the latter, it willflow around beneath the flange F and between the sleeve S and theoutside of 'the' inner wick-tube]V and thence back intothe oil-chamberA. Y -Heretoforevin v"lamps of this kind where this perforated sleevehas not `been employedthere has been a t'endencyon thepart of the oil tocreep over, in small quantities, the top of the inner wick-tube, thusescaping outsideof the lamp,

thereby causing more orless trouble andan(y v noyance. My invent-ionremoves, this objection and reconv'eys, 'as above stated, all the` oilthat has left the Wick back into the chamber without permitting any ofitto escape.V

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent, isy The combination, With the innerWick-tube, I, and the outer wick-tube,'0 of theV shorty sleeve/S,fitting around the upper` endV of the inner. wick-tube Ainside thewick-space and havingahorizontalinwardlyprojectingfiange, F, resting onthe top of the inner wick-tube,

and formed with perforations s, the said per- Y forationsprovidingpassages for" conveying the surplus oil from the upper part` of the4wick-spacetothe surface of the innerfwiclc. tube, and the angepreventing the oil from' overflowing the top of the inner wick-tube,
